Be it known that I, CECIL MILTON 'HEP- won'ru, subject of the King of England, residing at 17 Cecil Court, Charing Cross, London, England, have invented a certain new and useful Apparatus for Use in Synchronously Operating Combined Kinematographs and Sound-Production Apparatus, of which the following is a specification.

This invention. relates to apparatus for use in synchronously operating combined kinematographs and sound production apparatus such as gramophones or the like.

According to this invention apparatus for the purpose described consists of two members arranged to receive reciprocating motion from the kinematographs and sound production apparatus respectively and thereby engage and operate an intermediate member in such a way that thel atter is not moved in a linear direction when the movements of the kinematograph and sound production mechanism are synchronous, but does receive such motion when the move The invention will best be understood by the following description taken in conjunction with the accompanying drawings which illustrate one method of carrying this invention into effect and in which Figure 1 is an elevation showingthe front of the apparatus. Fig. 2 is a plan view of the same, Fig. 3 is an elevation showing the back of the apparatus with a portion of the lamp bulb broken away toshow the transparent portion behind the pointer, Fig. 4 shows in plan part of a gramophone disk with a special starting arrangement, Fig. 5 is an elevation of one form of contact making device as attached to the gramophone, F'g. 6 is a plan View of the same, Fig. 7 is a View showing one form of contact making device attached to the kinematograph, Fig. 8 is a diagram showing the electrical connections between the differentparts of the apparatus. Fig. 9 is a detail section on the line 99 of Fig. 5

Referring'to Figs. 1 and 3 mounted on a base A is a frame work comprising two upright posts A and A joined together by four horizontal bars A. The spindle B of a ratchet wheel B is adapted to slide between the twoupper and two lower of the bars A respectively, and it can also rotate.

To the post A a lug A is attached and an armature C is pivoted on a'pin C in this lug. Attached to a pin C at the opposite end of the armature C 'a pawlD is pivoted and this pawl engages the ratchet wheel B. A continuation of the pawl D around its pivot is formed into a hook D to which a spring E is attached. A second pawl 'F engages the same side of the ratchet wheel as the pawl D, the pawl F being pivoted at F to :1 lug on the post A This second pawl prevents a backward movement of the ratchet wheel B due to the friction of the pawl D. A continuation of the pawl F around its pivot is formed into a hook F to which the opposite end of 't-he'spring E is attached as shown. An electro-magnet G is fixed to the base A so as to operate-the armature C. A lug A is fixed to the base A and to a point H thereon an armature H is pivoted. At the opposite end of the armature H a pawl I is pivoted and this pawl engages the ratchet wheel B. A continuation of the pawl I around its pivot is formed into a hook I to which a spring .1

is attached. A second pawl K engages the same side of the ratchet wheel B as the pawl I, the pawl K being pivoted to the lug A on the post A. This pawl also prevents a backward movement of the ratchet wheel due to the friction of the pawl I. A continuation of the pawl K around its pivot is formed into a hook K, to which the op-.

posite end of the spring J is attached. A second electro-magnet L attached to the base A operates the armature H; A pointer M is pivoted to a link 'M which in turn is pivoted to the post A. This pointer is en gaged by the spindle B of the ratchet wheel B so that any longitudinal movement of the ratchet wheel spindle will cause the pointerto be moved to the left or right as the case may be. A transparent disk is attached to this pointer, one half M of thisdisk being of one color and the other half M of another color. An electric lamp M is arranged behind the pointer, the bulb of this lamp being covered with an opaque substance except for a small circle which 'is hidden by the pointer when the latter is in its middle position as indicated at m in Fig. 3. hen the pointer is displaced to one side or the other, one half M or M of the transparent screen is illuminated and consequently; a light of one or the other color shown.

- In Fig. 4 is illustrated the means pref-.

er'ably employed-for assuring correct starting'of the gramophone record. The gramophone needle is placed in the slot. R and practice are illustrated in Figs. 5 to 7 Referring toFig. 5 a bracket P is constructed so that one end P can rest on the gramophone case. The other end is provided trated, four times in every revolutions. As

with a spindle rotatably mounted therein to which is attached a toothed wheel P engaging with -a second toothed wheel P The ratio of the number of teeth in the toothed wheels is such that when the gramophone and kin einatograph are operated synchronously each of the electro-magnets is energized the same number of times per second. It is obvious that instead of employing only two toothed wheels more than two may be employed. The spindle P rests on the disk pin of the gramophone and has av small projecting ridge P atits end. This ridge enters a slot in the disk pin P. By this means the spindle is rotated as the disk pin rotates. Fixed to the second toothed wheel P is a contact maker N and one or more springs N are made to press against it. This contactmaker consists of a disk of insulating material N with metallic contacts N in the form of segments secured therein, opposite contacts being connected in any convenient manner. A circuit is established between the battery and the electro-magnet G when the springs N press against two opposed contacts on the contact maker. In this manner the speed of operation of the gramophone controls the number of times per second that the electro-magnet G is energized. The bracket P is made so that it p can be lifted right of; the gramophone case in order that the be changed.

An improved advantage of the electric gramophone records may contact making mechanism just described is that it may be easily fitted to existing gramophones.

In Fig. 7 is illustrated one form of contact maker 0 as applied to a kinematograph. It is of the same type as the contact maker N and is fixed to the spindle that is rotated by the handle which operates the kinematograph. Bearing on each side are two springs O mounted on blocks 0 of insulating material and .having terminals 0 for the necessary electrical connections. Contact is made in a similar manner to that described in connection with the gramophone contact maker and as the handle of the kinematograph is rotated it controls the number of times per second that the electro-magnet is energized.

Fig. 8 1s a diagrammatic illustration of the apparatus and its connections, arranged according to this method of carrying thls invention into effect, and the method of operation will be described in conjunction therewith. As the contact makers\N and O rotate their respective electro-magnets G and L become energized whenever connectron is made with the battery throu h their respective contact makers, and this takes place with the form of contact maker illusthe armature C of the electro-magnet G for example, is attracted, the pawl D attached thereto passes over a tooth on the ratchet wheel B. When the armature C is released owing to the action of the spring E the ratchet wheel is rotated through a distance corresponding-to one tooth. The same operatlon'takes place with the armature H of electro-magnet L when the latter is energized. If'the speeds of the contact makers N and O are alike, the armatures operated by their respective electro-magnets will rotate the ratchet wheel B but will not move it longitudinally. However, if the kinematograph is being operated at too high a speed its contact maker will make a higher number of revolutions and consequently make electrical connection more frequently than the corresponding contact maker on the gramophone. The result. of this will be that the armature H will move its pawl I more frequently than the armature lCmoves its pawl D, and the ratchet wheel receiving a greater number of thrusts at one side than it does at the other will be moved in a longitudinal direction. lVhen this takes place the pointer M attached to the spindle of the ratchet wheel will move so that one or the other half, M or M of the transparent screen will appear in front of the illuminated circle on the electric lamp, thereby indicating to the operator, according to whichever color is assigned to the kinematograph, that such kinematograph is being worked too quickly. Ifthe operator then lowers the speed of operation of the kinematograph and allows the gramophone to j iogra-ph' may be controlled manually so as to bring the movements of the two in synchronism. The longitudinal movement of the ratchet wheel may, however, be utilized so as to keep the kinematograph and gramophone in synchronous operation. That is to say, the movement of the movable member may be utilized in any manner known to those skilled in the artto synchronize the speeds of the two i'nachines.

Obviously it is not intended to restrict the use of a commutator to that type of kinematograph which is operated by a handle, as acommutator can quite easily be fitted to an electric motor used to operate the kineniatograph.

Preferably the indicating or controlling device described above is employed in 'com bination with the contact-making mecha; nism just described, but it is within this invention to employ either independently.

It is obvious that various modifications may be made in the methods of carrying this invention into effect, those described above being merely by way of example.
